Problem statement: The aim of this study was to examine the blood biochemical and&#13; physiological changes that occur during competitions in elite handball players-men in a specific kind of&#13; anxiety state. The grounding, elaboration, verification and evaluation of a scientific concept based on&#13; psychological, physiological and biochemical guidance of the effort in competitive handball in order to&#13; generalize it at national level, imply the following: Establishing if and in which measure, the stress factors&#13; that act upon handball players during the official competition influence the modification dynamics of certain&#13; physiological factors being in direct correlation with effort capacity and focusing on the capacity of&#13; influencing, controlling and directing the stress factors in the sense of obtaining certain physiological&#13; parameters values necessary for a great performance. The research has emphasized the fact that this method&#13; of studying the factors that intervene in obtaining performances in handball is not yet applied on a national&#13; level, this aspect not being a priority for the specialty federation representatives, although this kind of&#13; collaboration with specialists from other fundamental areas, associated with competitive sports, has given&#13; world-wide remarkable results in other sports. Approach: The selected subjects for the experiment were&#13; male handball players in the Internal Championship-Romanian National League-male. Our experiment&#13; focused on each teams ten most valuable players (The first seven title players and the first three most&#13; valuable reserves), resulting 50 subjects from the male teams. The selection criterion was number of times&#13; they played as title players in the Romanian Championship games, their participation in centralized&#13; training sessions with the Romanian representative teams, as well as their play in the Romanian National&#13; Team. Blood samples were drawn 3 min after finishing the match in order to determine pH, oxygen partial&#13; Pressure (PO2), carbon dioxide partial pressure (PCO2), concentration of Hydrogen Carbonate (HCO3&#13; -),&#13; Base Excess (BE), Standard Base Excess (SBE), Standard Bicarbonate (SBC), Lactic Acid (LA) and&#13; relation SBC/HCO3&#13; -(R). Conclusion/Recommendations: After match all parameters studied changed their&#13; value significantly (p<0.001) in all teams. These results demonstrate that handball demanding in a highly&#13; aerobic with a considerable anaerobic component (as in official competition) requiring high lactate&#13; tolerance. Training programmed should reflect these demands placed on players during competitive matchplay.&#13; The purpose of this study was accomplished, confirming some of theories in the sportive from a&#13; psychological point of view of approaching the sportive competitions. Data can represent a starting point&#13; in thorough study of the handball coaching principles
